To all whom it may concern:

Be it known that I, AUGUST A.

I What I claim as new is:

The device is peculiarly adapted for use by 1. In a powder measuringdevice, the comdruggists in measuring out prescription powbination ofthe measuri g cylinder; a plunger ers.

The stem 3 1s screw threaded at 8, and nuts on the screw for limltingthe movement of the sides of the loop, and the extent of the 9 and 10are arranged above and below the side 7, so that any movement of theside 7 outward movement of the plunger.

3. In a powder measuring device the comcarries with it the stem 3 andplunger 2.

In use the operator grasps the handle bination of a measuring cylinderhaving a perforated head; a plunger in the cylinder; a formed by thespring loop and presses the stem on the plunger extending through thecylinder into the powder. The powder com pletely fills the cylinder andwill adhere to perforation in the head, the head forming a guide for thestem; a handle in the form of a the walls thereof, so that it may beremoved from the mass of powder. The operator spring loop, one side ofthe loop being secured to the cylinder and the other to the then ressesdown on the side7. This moves the pIunger in the cylinder and dischargesthe powder in the cylinder.

It is desirable'to vary the extent of the movement of the plunger 2, soas to vary the charge measured .bythe device. It s also desirable tohave the plunger 2 so adjusted as to move to a position flush with thebotstem.
